SPINNING 0R TWISTING SPINDLE WITH A DEAD SPINDLE SHANK Filed May 19, 1961 4 Sheets-Sheet 4 United States @stent Qi and The present invention relates to a spinning or a twisting spindle with a dead spindle shank which has journalled thereon two rotors for supporting the lower and the upper spindle sleeve end, the rotor receiving the lower spindle end being adapted to be driven.

An increase yin the output of spinning or twisting machines causes the Ioccurrence of a number of problems. The adaptability of a spinning or twisting machine to a wide range of different spinning materials and to a wide range or" yarn numbers to be produced requires the adaptation of the creel, the driving mechanism of the main drive, of the spindle drive, and of the spindle. With regard to the Creel, the driving mechanism, the main drive and in part also the spindle drive, the problems involved have been solved at least to a certain extent, but problems concerning the spindle itself have not yet been satisfactorily solved so as to allow an adaptation thereof to a wide range of spinning materials `and yarn numbers.

The spindles heretofore known are generally applicable within a rather limited working range only, and this is due to their dimensions and the damping devices asso ciated therewith. Therefore, while it is possible to universally employ a spinning machine with its creel, driving mechanism `and main drive, the spindle itself permits its employment only within a rather narrow range with regard to a variation in the speed, a variation as to its length and also a variation as to the weight of the cop. If it is desired to exceed such a range, it is required to exchance all the spindles for other spindles which will be suitable for the new conditions of operation. ln addition thereto, the output of a spinning machine depends on the relationship between running times and periods of stoppage, which relationship becomes more favorable when the yarn body is increased.- The increase of the yarn body or cop, however, automatically makes the withdrawal of the increased yarn body more difficult so that the time of stoppage required for the withdrawal of the yarn body cannot be reduced but is rather lengthened. The relationship between running time and period of stoppage can, therefore, not be Varied to the desired extent. A change lof these values to the desired extent can be ob tained only when, on one hand, the spindle itself is adap table to a wide range of materials to be processed and a wide range of yarn numbers. However, simultaneously with the increase in the yarn body, it is also necessary to faci ate the withdrawal operation of the yarn body. lt is only the solution of this important problem, namely, the creation of a universally employable spindle, which will yield a favorable relationship between production times and periods of stand still and which thus will be able to increase the loutput of spinning or twisting machines.

lt is, therefore, an object of the present invention to provide a spinning or twisting spindle which will over come the above mentioned diculties.

lt is another object of this invention to provide a uni versally applicable spindle which will make it possible greatly to increase the range of applicable yarn bodies and yarn numbers.

These and other objects and advantages of the invention will appear more clearly from the following specification in connection `with the accompanying drawings, in which:

Patented Feb. 4, 1954 HG. l illustrates a spinning or twisting spindle according to the invention with a short sleeve.

FIGURE la illustrates the uppermost portion of FIG- URE l but on a considerably larger scale than FIG- URE l.

ElG. 2 represents a spinning or twisting spindle according to PEG. l but with a long sleeve.

3 is a modified spinning or twisting spindle which is longitudinally adjustable.

FIGS. 4 and 5 respectively illustrate in two dierent positions a spinning or twisting spindle with adjustable long shank.

EG. 6 is a spinning or twisting spindle with a hollow lower rotor.

FlG. 7 shows a spinning or twisting spindle of 6 with downwardly moving inner long shank.

FlG. 8 shows on an enlarged scale the support of a sleeve in the hollow lower rotor prior to the mounting of the sleeve, and i llG. 9 shows the mounting of FIG. 9 in the hollow lower rotor.

The invention concerns a spinning or twisting spindle with dead spindle shank on which two rotors 'are journalled for supporting the lower and the upper `end of the spindle sleeve. Of these two rotors, that rotor which supper the lower sleeve end is adapted to be driven and is in conformity with the present inventionV so designed that the dead spindle shank is composed 'of two individual shank sections which are supported coaxially independently or each other and `on which independently or" each other each rotor is journalled.

The term spindle sleeves as it applies to the present invention also comprises any type of yarn carriers which may be empioyed in the manner of the heretofore known nro.

spindle sleeves, in other words, all yarn bodies with yarn carrier functions. Spindle parts and spindle sleeve when assembled form the spindle body with the customary spindle function.

More specically, according to lthe present invention, one of the two shank sections may with radial play embrace rthe other shank section and move only that end thereof which faces the other shmk section journalled coaxially but independently of the other shank section. Independent journalling of the two shank sections brings about a considerable simplication in `the journailing ar- Irangen'ient and has the advantage that the rotating sleeve adjusts itself automatically and independently of the journalling `of the shank sections connected thereby to a certain aids of rotation corresponding to the rotating masses with the result that the bearings will be under completely uniform load. The sleeve may be able to carry out a pendulum movement to la certain extent as a requirement for an automatic adjustment to an axis of rotation which coincides with the axis of gravity of all rotating parts including the spinning sleeve.

Furthermore, according to a further feature of the invention, one of the shank sections may be designed as outer hollow shaft which is stationarily held on the spindle rail, said spindle rail carrying the rotor for supporting the lower sleeve. rlhe other shank portion is designed as inner longitudinal shank, the upper end of which carries the upper end of the rotor for supporting the upper sleeve end.

The said inner longitudinal shank entends coaXially through the outer hollow shank, and the spindle rail is journalled below said spindle sleeve.

The subdivision of the carrier for a spindle sleeve in two shank sections which are joutnalled independently of each other in a coaxial manner and which are connected to each other along a closed path by the spinning sleeve itself, and of which at least one rotor is adapted to be driven, yields a number of further advantages. One

of these advantages is realized due to the `fact that the inner longitudinal shank is, in conformi-ty with the invention, adjustable to different sleeve lengths so that the two shank sections, without any change` in construction, may be employed for various sleeve lengths.

According to Ia lfurther feature of the present invention, the inner longitudinal shank may have its lower end axially -displaceably journalled which feature will be of importance whenever the inner longitudinal shank constitutes the stationary shank portion, the treeV end of which only carries a rotatably journalled rotor as supporting body' for the sleeve.

The axially displaceable support for the inner longitudinal shank may be obtained by having the inner longitudinal'shank with its lower end movable into a plurality Vof. positions into 'a holding bushing mounted on the bottom `side of the spindle ra'il, While locks or like arresting means are provided for arresting said inner longitudinal shank in its respective position. Another type of adjustment may be obtained by having at least the lower end of the inner longitudinal shank provided with a thread engaged by an adjusting nut which is operable independently of the spindle rail.

Finally, it is possible, by means of nuts, to fasten the inner longitudinal shank in an axially adjustable manner to an adjusting independently of the spindle rail.

According to a further feature of the invention, the inner longitudinal shanks of a plurality of spinning sleeves may have their lower ends connected to a common rail independently of the spindle rail, which common rail is adjustable as to height so that, by lifting or lowening said common rail, an entire spindle row may be adjusted as'to dilerent sleeve lengths. Such an arrangement has the yadvantage that, by lowering the said rail, the inner longitudinal shank may be lowered rto such an extent that the mounted sleeves for purposes of removal will not any longer have to be displaced upwardly in a longitudinal direction overV the inner longitudinal shank in order then to be removed. It is rather sufficient to lower the inner longitudinal -shank so that fthe sleeve will become free from the lower rotor merely by tilting. Correspondingly, also, the mounting of new sleeve-s will be 'considerably simplified because they have to be slipped over the re- Vmaining short end of the inner longitudinal shank only.

eir proper location and holding will be eeoted automatically when the inner longitudinal shank is moved upwardly to such an extent that the ytree sleeve end engages the inner longitudinal shank, whereas the other sleeve end will be held `tast by the lower rotor.

' The last mentioned `arrangement may 'furthermore be improved by making the inner longitudinal shank nearly or completely movable downwardly out of the outer hollow shank.

According to a further development of the invention, the inner Ydiameter of the outer hollow shank corresponds at leastrto the maximum diameter of the spinning sleeve while said spinning sleeve together with the inner longitudinal shank is 'movable from below into the outer hollow shank. ln this way, new sleeves may be moved in from below so that slipping on of new sleeves may be directly combined with the removal of the cops. When the inner longitudinal shank is moved outwardly in downward direction, the cop will be freed from the inner longitudinal shank and may' be tilted laterally directly from the lower rotor without the necessity of being lifted olf. This in itself represents a great advantage because such lifting off requires considerable force when large cops are involved and, thus, represents a time-consuming and eumbersome operation.V inasmuch as with the tilting oi simultaneously also the inner longitudinal shank is moved downwardlyl where it wil-l be free, it is possible simultaneously -to mount a new sleeve which will then move into its working position from below. In its moved-in position the new sleeve will engageV the lower rotor so that both sleeve ends will be supported. In this connection, it is immaterial whether the sleeve is rotated by a rotating and driven lower roto-r or whether a second longitudinal shank is dniven and rotates the lower rotor through the intervention of the sleeve.

The subdivision of the support for the spinning sleeve into two shank portions, namely, into an outer hollow shank and an inner longitudinal shank brings about further advantages, particularly when the inner longitudinal shank .is supportedrby an adjustable rail adapted to VbeV lower circumferential speeds will occur even if the speed of the spindle is very high.

Referring now to the drawings, the same reference nu-V merals are applied to the sa-rne parts throughout the various figures. The various arrangements shown in the drawings Vsubstantially comprise a spindle rail 1, spinning sleeves 2, 2.', a brake lever 3 for braking the spindle and thereby the sleeve, a lbrake nut 4 and a counter brake nut 5. The spindle comprises the outer hollow shank rwith the running sleeve 7 of the whorl. The lower whorl hoard is designated with the reference numeral 8, whereas the reference nuimerns 9 and 9 designate the upper v/horl board 'between which .there is located the running sleeve 7 of the whonl. .'Ilhe whorl is journalled in anti-friction bearings 10. Sleeves 2, 2 have their lower end supported by the rotatable supporting members 11, 12, 12. The reference numeral 13 designates a spring ring disc and the yreference numeral 14 designates a hollow shalt nut. All

igures comprise the above mentioned elements.

Referring more speciiically to the embodiment of FIGS. y

' bushing 1S which is closed `at the bottom and the interior of which is provided with annular gnooves 15 having mounted therein rings 17 of elastic material. The said rings 17 extend around the lower end of barS- which is provided with threads or 'annular ignooves, said bar 118 forming the inner longitudinal shank. The employment oi elastic rings 17 makes possible a certain lateral deviation of the lower end of the inner longitudinal shank 13 so that said inner 'longitudinal shank will be able automatically to adjust its axis to the line of lgravity of all parts rotating therewith. Directly adjacent to the 'lower end of the hollow shank 6 there is a spring ring 119 w-hich, similar to the rings 17, engages la-n annular groove 2li or the thread of the inner longitudinal shank l. ln this wa the location of the inner longitudinal shank is clearly detenmrined as to height and may be adjusted as indicated in FlG. 2. Due to the possibility of changing the VpositionV of the inner longitudinal shank 1S asy to height, sleeves of diffe-rent lengths maybe employed. Thus, PiG. l shows `a short sleeve 2, whereas FlG. 2 shows mounted on the spindle -a long sleeve 2. The upper end of the inner longitudinal shank le has arranged thereon a sleeve supporting body -Zll which forms a rotor and is freely rotatable. To this end, referring Ito FIG. la, the sleeve supporting body 21 comprises -a central pin 22 with head 23 which pin is axially inwardly direc-ted. Pin 22 extends through bore Zd of a bushing 25 mounted on the end of the inner longitudinal shank l and thereby is secured against withdrawal. The nozzle-shaped cross section of bore 24 will Within certain limits permit pendulum movements of the rotatable sleeve supporting body or member 21. The axial pressure which is eftective through the intervention of the supporting member 2l and sleeve 2, 2' is absorbed yby the supporting plate 26 provided with a spherical surface. The lower end of the spinning sleeve 2, 2 rests on the rotatable supporting body or member lll the outer surface of which is slightly anchored so as to allow an automatic adjustment of the spinning sleeve 2, 2' in conformity with lthe line of gravity. yFor compensau'ng differences in dimensions of sleeve 2, 2 or member 11, and to aid member 11 in conveying its rotational movement upon the spinning sleeve, for instance one or more sleeve couplings 27 may be employed which will not laiicect the Withdrawal of sleeve 2, 2'. Such coupling 27 comprises a spring-urged ball which, while being located in a cavity in member 11, slightly protrudes outwardly beyond the periphery of member il and is pressed against sleeve 2, 2.

As will be evident from the drawings, the inner longitudinal shank 18 extends with radial play through the hollow shank 6. The inner longitudinal shank 18 is supported in sleeve i merely by the spring ring 19 and the elastic ring 17. The inner longitudinal shank 1S is furthermore supported at its outer free end by means of the spinning sleeve 2, 2 through the intervention of the rotatable sleeve supporting member 21, said spinning sleeve representing the only connection between the inner longitudinal shank 18 and the lower rotating member. The said lower rotating member is formed by the rotatable whorl elements 7, 3 and 9 in combination with supporting member 1l. and carried thereby.

As to the raising and lowering of shank or spindle 18, it will be appreciated that this is eiected manually as ar as the embodiment of FlGS. l and 2 is concerned. However, with the embodiment of FIG. 3, this raising and lowering action is eiected by a worm 37 and worm wheel 3o which latter forms the spindle nut for the thread 29. With the embodiment of FlGS. 4 to 7, the said raising and lowering action is eected by raising and lowering rail 53.

Aside from the fact that the spinning or twisting spindles according to the illustrated embodiment may thus be used for spinning sleeves of different lengths, it will, due to the way in which it is journalled, bring about the advantage that the sleeve will be able during its rotation, without difficulty, to adjust its axis automatically with regard to the line of gravity of all rotating parts. As a result, a considerably higher speed may be selected than f is obtainable with the heretofore known spindle bearings. rl'his is furthermore aided by the fact that the mass of the rotating spindle parts is considerably less than that of the heretofore known spindles. The reduction in weight of the rotating parts will, particularly with spindles for large cops be of particular importance.

According to the embodiment of HG. 3, the inner longitudinal shank and the lower rotating member are nearly of the same construction as with the embodiment according to FIGS. l and 2. The dierence between the arrangement of 3 and that of FIGS. l and 2 consists primarily in the design of the upper whorl board 9 which consists of one piece with the rotatable supporting member 12. The said rotatable member l2 represents a hollow body open at the top and surrounding the lower end of sleeve 2 while serving simultaneously as winding-on cup. An elastic hollow ring 2S is interposed between member l2 and sleeve 2 and serves as a sleeve coupling. This sleeve coupling coupling sleeve 2 to member 12 also furnishes the possibility of causing the spinning sleeve 2 during its rotation automatically to adjust itself as to the line of gravity of all rotating parts. i

The lower end of the longitudinal shank i8 is below the spindle -rail 1 provided with an adjusting thread 29. The thread 29 is engaged by a nut 3i? designed as worm wheel which by means of its hubs 3l and anti-friction bearings 32 is journalled in the adjusting rail 3?. A uniform distance between spindle rail l and adjusting rail 33 is assured by sleeve 3d which surrounds the inner longitudinal shank l below the spindle rail i and by means of its upper end rests on 1a collar 35 of nut 14. The lower end 36 of sleeve 34 rests in the supporting member 33. The worm wheel 3@ meshes with worm 37. By rotating worm 37, the worm wheel 3@ is rotated whereby the inner longitudinal shank i3 is rotated so that said shank i3 will move axially in one or the other direction. This furnishes the possibility of varying the axial length of the inner longitudinal shank 18 above the spindle rail 1 and thereby makes it possible to adjust the axial length or" shank 18 in conformity with the length of the respective employed sleeve 2.

With the embodiment according to FIGS. 4 and 5, those parts which are arranged above the spindle rail l `correspond to the parts according 4to FlGS. 1 and 2. Below the spindle rail, there is provided an adjustable rail S3 which is adjustable to difterent heights. Fhtedly connected to rail 53 is the lower end of the inner longitudinal shank i8. This connection is eiected by means ot the thread 54 and nuts 55. According to FIG. 4, the inner longitudinal shank i8 occupies its moved-out position, the spindle sleeve v2 having its lower end on the rotatable supporting member li. The upper end of spindle sleeve 2 rests on the sleeve supporting member 2l. The sleeve supporting member 2l is rotatably mounted on the inner longitudinal shank 18. lf the lower rotatable supporting member is driven through the intervention of the running sleeve '7 of the whorl, also sleeve 2 will be rotated which in its turn causes the sleeve supporting member 2l. to rotate. Thus, the spindle sleeve 2 forms the driving connection between the sleeve supporting member and the lower rotatable supporting member.

According to the arrangement of FIG. 5, the inner longitudinal shank i3 is due to a lowering of the adjusting rail 53 lowered to such an extent that the sleeve supporting body 2. ot the inner longitudinal shank i3 rests upon the rotatal le supporting member il. ln this position, the spindle sleeve 2 may be mounted without any difficulties and may also at the end of the spinning operation, when the cop is wound onto vthe spinning sleeve, be withdrawn merely by lateral tilting. This means a considerable simplification or" the handling because it is not necessary any longer to move the heavy cop weight upwardly over :a long sturdy sleeve and to remove the cop weight over said sleeve. i

FIGS. 6 and 7 illustrate an embodiment which diers from the embodiments described so far in that the inner diameter of the outer hollow shank 6 permits a play-free passage of a sleeve 2. Aside from the fact tha-t the diameter values of the parts of the lower supporting members `are dierent, there are provided the brake lever 3, the braking nut 4i, the braking counter nut 5, the running sleeve '7 of the whorl, the lower whorl board S, the two whorl anti-friction bearings lil, the spring ring disc 13 and the hollow shank nut f1.4. The upper whorl board 9 consists of one piece v ith the sleeve supporting member l2 in which the lower end of sleeve 2 may rest through an elastic hollow ring 2S. The inner longitudinal shank i8" is designed as a hollow tube which by means ot a thread and nuts 55 is rmly connected to the adjusting rail 53. The other end of the hollow inner longitudinal shank lil supports the conical sleeve carrier 57 through the intervention of the anti-friction members S5. The lower end of sleeve carrier 57 is radially supported in the interior of the sleeve supporting member l2' by an elastic hollow ring 2:3 when the inner longitudinal shank l has in conformity with FIG. 6 passed through the outer hollow shank. The outer upper end or" the inner longitudinal shank i5 together with the conical hollow supporting shank l" is provided with a cover disc S8.

As will be evident from mit?. 7, the inner longitudinal member 57 carried thereby may Ibe lowered :downwardly so that the spinning sleeve 2 with the cops 59 thereon may be removed by lateral tilting. Thereupon, a new sleeve 2 can bemounted in a very simple manner, and the inner longitudinal shank with the sleeve carrier may be moved into the position shown in FlG. 6. It is, however, also possible to move the inner longitudinal shank 13 completely downwardly and to place the spinning sleeve 2 elow thes-pindle rail l upon the inner longitudinal shank and then to move said spinning sleeve 2 into the position shown in FlG. 6. lIn this way, there is created the possibility of combining with the tilting oil of spinning sleeve 2 with cop 59, a mounting of a new spinning sleeve 2 on the inner longitudinal shank in lowered condi-tion so that the removal of the `,cops and the introduction of la new spinning sleeve may follow each other directly which fact means a considerable saving in time. y

in addition thereto7 there is created the possibility of ascertaining the weight of the cop without having to remove the spinning sleeve with the cop from the machine. To this end, it is merely necessary to `design the adjusting rail 53 as a balance or a scale beam. lf tirst spinning sleeve 2 is mounted on the hollow sleeve body 57, the spinning sleeve 2 is moved through the outer hollow shaft to such an extent that the spinning sleeve will not engage the lower rotatable supporting body. Thereupon, the sleeve weight is ascertained or determined. Subsequently, the inner llongitudinal shank is lowered to such an extent that the spinning sleeve 2 moves into the posit-ion of FIG. 6. In this position a spinning operation may be carried out until the cop S9 has been formed. Following the completion of the spinning operation, the adjusting rail 53 together with the inner longitudinal shank d8 and the spinning sleeve `2 with cop 59 is moved upwardly to such an extent that the spinning sleeve 2 will separate from the lower rotatable supporting member namely from the elastic ring 28 and the rotatable supporting member 12. By means of the adjusting rail 53 which is designed as scale or balance arm, the total weight will then be ascertained so that the diderence of this weighing operation and .theV first weighing operation will determine the cop weight proper. Subsequently, the `cop 59 with spinning sleeve 2 is tiltedoff, and a new spinning sleeve 2 is moved in through the outer hollow shank.

FIGS. 8 and y9 illustrate in detail and on an enlarged scale Vthe design of the hollow elastic ring 28 by means of which the spinning sleeve l2 or the hollow spinning sleeve carrier 57 is supported in the rotatable supporting member 12'.V 8 illustrates the supporting member 57 prior to the insertion of the spinning sleeve 2 while FIG. 9 illustrates the supporting member 57 after the insertion of the spinning sleeve 2. n the last mentioned instance its cross section is deformed in an oval manner. lt thus brings. about a tolerance compensation and assures the rotation while acting in the manner of a ball joint so that the rotating spinning sleeve Z is able automatically to adjust itself in conformity with the line of gravity ot all rota-ting individual elements. These hollow ringsmay, of course, also be replaced by spiral springs or similar spring elements.
